It's been difficult for boaters with bimini tops to display water sports flags effectively, until now. Instead of manually holding the flag below the canvas top, your flag will fly above the top, enabling other boaters to see it. It also frees your hands to tend to other activities. It is crafted from polished anodized aluminum. Attach it in seconds to one of your boat's bimini top support poles with the 2 zip ties included. The soft polymer caps are designed to eliminate rattling. Designed to be used with Airhead's new 4' water sports flags, not included. Also great for pylon extensions.
